    摘要: A method for position determination with the aid of GPS satellites, including reception processing of a GPS satellite signal L2 modulated by an encrypted code Y having a key not available from the GPS satellite, so as to assess a delay of the signal L2 with respect to the signal L1 and to deduce therefrom the magnitude of the ionospheric effect so as to take account thereof and improve the accuracy of the location finding. This processing includes reducing the signal L2 to a lower band and in despreading the signal L2 by means of the non-encrypted code P produced locally in reception by a local generator of a non-encrypted spreading code P synchronized with the code Y (encrypted P) transmitted, with the aid of a phase lock loop with three parallel paths: a first path demodulated by a precise version of the locally produced non-encrypted spreading code P, a second advanced path demodulated a first time by an advanced version of the locally produced non-encrypted spreading code P and a second time by the demodulated signal of the precise path, and a third delayed path demodulated a first time by a delayed version of the locally produced non-encrypted spreading code P and a second time by the demodulated signal of the precise path, synchronization being achieved by searching for an equality of power of the carrier of the signal L2 at the output of the advanced and delayed paths.

    摘要: The invention relates to a radiofrequency receiver, notably for satellite positioning applications, needing to operate in an environment where interference is dense, notably when it involves pulses transmitted by DME beacons. Below the useful signal suppression threshold, amplitude or power are inverted to improve the dynamic interference response time. Advantageously, the useful signal suppression threshold and the set point power or amplitude are determined by analyzing the amplitude or power probability density function in its part enriched with low amplitude/power samples.

    摘要: A receiver for determining position based on GPS satellites and GLONASS satellites. The receiver architecture includes a radio reception chain with an antenna, frequency conversion circuits, an analogue/digital converter operating at very high rate for the GLONASS pathway, and a signal processing circuit with several general-use channels capable of receiving both GPS signals and GLONASS signals. This circuit uses a programmable pseudo-random code generator and a phase servocontrol loop which uses a local oscillator to produce a local transposed carrier frequency; this oscillator is controlled in such a way as to be able to impose a start frequency for the acquisition of a satellite signal.
